Application Iilcd December 24, 1886. Serial No. 222.433. (No model.) I

To all whoml it 11mg/ concern:

` Be it known that I, ALLEN RAMsAY GUsICK, of Allendale, in the county of Wabash and State of Illinois, have invented a new and useful Improvement in Combined Latch and Lock, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure l is a view of my improved device with the face-plate removed; Fig. 2, an external perspective view of a portion ofthe same, and Fig. 3 aper'spective View of the thumbbolt detached. Fig.4 is a top view of the bolt, showing the double bevels.

My invention relates to au improvement in combined latches and locks, wherein the special improvement consists in dispensing with one of the bolts ordinarily used in locks, and in lieu thereof I provide a single bolt and bevel the opposite faces of the front end, so as to avoid the necessity of reversing when used for right and left hand doors, the key forlocking and unlocking, and the knobspindle disposed so as to act -directly upon this bolt, a right-angled lever within the device connect-v ing with a second lever,which has a knob end projecting forwardly from the case for operating, so disposed as to be locked 4and unlocked by means of an ordinary key, this right-angled lever being, however, disposed with a dead-latch to be operated from the inside ofthe door, so that the bolt cannot be operated either by thel key or knob-spindle, all of which will now be fully set forth.

In the accompanying drawings, A represents the case of an ordinary door-latch provided with abolt, B, the extreme outer end provided with opposite bevel faces, so that it may be used on either right or left hand doors without reversing. This bolt is provided with a spring, C, so disposed that, except when the bolt is retained in position by the internal attachments,its normal position will be with the end projecting from the case, as shown in Fig. 1. The forward end of the bolt B, just within the case, is provided with a lug, D,so disposed as to come in Contact with the inner face of the case-flange, while the inner face, E, of the said lug is somewhat inclined. Above the 5o bolt B, I provide a lever, F, the upper arm,G-,

and provided with a suitable knob for operating, while a lower arm, H, is so disposed as to come in contact with the inner angled face, E, of the lug D, when the upper arm, G, of the lever is pulled forward, but which rests above the upper edge of the said lug D when the lever F is reversed.

lJust within the upper wall of the case I p'rovide a right-angled lever, I, pivoted near the lever F, just within the case, with the angled arm J projecting downwardly and having a recess, K, therein, Within which a lug, L, on the projecting arm of the lever F rests. The usual key-hole, M, is disposed through the case within the angle formed by the two sides of this lever I. rlhe lever F is provided directly opposite the center with two projecting lugs, N, so disposed that the wards of the-key will engage therewith when it is turnedin the lock. Upon the bolt O, to which the lever I is pivoted, is also pivoted'a bar, l?, which extendsdown and engages directly with the upper face of the bolt B, and the lugs Noi' the 1ever F are disposed immediately over the upper end of this bar l?. At the end of the lever I is a small bolt, Q, pivoted to the latchcase and operating in engagement With said lever, which bolt has an outwardly-projecting thumb-piece, R, extending ,through the top of the latch-case, while the inner endhas a shoulder, S, so that when the outer end is turned by means of the thumb-piece R the lever I will be held in position parallel with the upper wall ofthe case A, and it will be necessary to disengage the shoulder S from the lever I in order to reverse the levers I and F or the bolt B from the position shown. Lugs rI are placed near the end of lever I and project partly through the opposite face of the case A. By depressing these lugs the lever I may be reversed, unless the lever is firmly held by engagement with the shoulder S.

Having described my inventon,whatl claim as new isl. In a combined latch and lock, a bolt having an inwardly-projectinglug, in combination with a pivoted lever, F, adapted to bevmoved both by hand and key into operative engagement with said lug, a right-angled lever, I, pivoted upon the latch-case and engaging said lever F, and a bar, P, operating in conjunction IOO with levers F and I and engaging the upper face of the bo1t to retract the saine, Substantially as and for the purpose set forth.

2. In a combined latch and lock, the combi- 5 11ation,\vith a bolt having an inwardly-pr0 jeeting lug, a pivoted lever, F, adapted to be moved both by hand and key into operative engagement with said lug, a right-angled 1ever, I, pivoted upon the latch-case and engag- Io ing said lever F, and having` lugs T thereon projecting through the face of the latch-case,

of a bolt, Q, having a shoulder, S, for engagement with the end of the lever I, and a thumbpiece, R, projecting through the latch-case, substantially as and for the purpose set forth. 15

In testimony that I claim the foregoing I have hereunto set my hand this L12th day of August, 1886, in the'presenoe of Witnesses.
